By incorporating additional information that are captured and collected by volunteers with help of their smartphones (Volunteered Geographic Information, VGI), flood forecast-ing systems can be improved and forecast uncertainties can be minimized. This paper presents and discusses different concepts and methods for measuring relevant hydro-logical parameters with mobile smartphone sensors. In this context, the focus is on describing various image-based approaches for water gauge measurements.deText/Conference Paper
